well to help with your shine, there are a few herbs that will help. marshmallow root gives great shine, gives amazing slip and helps with scalp problems. stinging nettle is meant to help with shine, i just got nettle water today will use it after my shower, so see how that goes.
give your hair a blast with cold water when ya done with everything, this closes the hair and gives shine and helps with fizz

my hair: 3b, high porosity, high density and coarse hair (i think i finally figured that all out)
my hair loves conditioner only styling!
Oils and my own procuts are my hairs best friend
my hair goal length is bra strap length when curly.
